A Study on the Characteristics Comparison of Source/Drain Structure for VLSI in n-channel MOSFET
고 집적을 위한 n-channel MOSFET의 소오스/드레인구조의 특성 비교에 관한 연구
Abstract
Thw VLSI device of submicron level trends to have a low level of reliability because of hot carriers which are caused by short channel effects and which do not appear in a long-channel MOSFET operated in 5V. In order to minimize the generation of hot carrier, much research has been made into various types of drain structures. This study has suggested CG MOSFET (Concaved Gate MOSFET) as new drain structure and compared its electrical characteristics with those of the conventional MOSFET and LDD-structured MOSFET by making use of a simulation method. These three device were assumed to be produced by the LOCOS process and a computer-based analysis(PISCES-2B simulator) was carried out to verify the hot electron-resistant behaviours of the devices. In the present simulation, the channel length of these devises was 1.0
